Water Resistance Research of Anionic Polymerized PA6/ABS Alloy

Abstract:

Macromolecule modification activator was prepared using prepolymer of HTBN end capped by HDI biuret (N-75). Then the ABS/PA6 co-blend polymer was prepared by anionic polymerization with putting ABS resin into molten caprolactam monomer at the temperature of 160-180 °C and the sodium hydroxide being used as activator. Compared with PA6， the copolymer alloy shows obviously low water absorption and slightly reducing mechanical property after absorption， while the loss of mechanical property is lower. The SEM analysis reveals that the reaction insitu compatibilization reduces the interfacial tension between PA6 and ABS and makes the ABS grain smaller and more uniform dispersion in PA6.
